Classical Chernoles period finished c. 500 BC, corresponding to a simplification in the material culture, interpreted to represent a pauperization due to the political domination of the forest-steppe communities by Scythians. In these latter stages, we see an increase in fortified settlements, perhaps representing a defensive measure against the nomads (with earthen ramparts, ditches and timber walls). Despite the difficulties, settlement density actually increases, and the socio-cultural traditions continued.
